LINDGREN,,OF \VESTERN SPRINGS, ILLINOIS, ASSIGNOR T GOODMAN MANU- FACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS CUTTING AND" LOADING MACHINE Application filed August 11, 1928, Serial No. 298,920. Renewed July 29, 1931.

I The inventionherein described is especially adapted to machines of the overcutting or slabbing type, which are more particularly I used in cutting slate or. dirt bands in the coal face. The plate mixes with the coal and causes great trouble and expense in that it has to be removed by hand either at the mine face or outside at the tipple. My invention eliminates this hand operation and provides a means to, ather these cuttin s and conve 7 them to a point remote from the face of the coal.

My invention may best be understood with reference to the accompanying drawings,

wherein: t

Figure l is a top plan view of the device embodied in my invention with the cutting element at right angles to the longitudinal axis of the truck and with parts broken away 0 to more clearly show my invention;

Figure 2 is a front end'view ofthe device shownin Figure 1;

Figure 8 is an enlarged fragmentary view of the cuttings deflection means used in my invention; I

' Figure 4 is a sectional View taken on'line 4+4 of Figure 3; and

' v Figure 5 is a partial enlarged fragmentary sectional view looking from the-front end of the machine showing certain details of construction of a portion of the device embodying my invention. I

eferring now more particularly to the drawings, it may be seen that the device embodying my invention is applied to a mining machine of the well known overcutting or slabbing type, andcomprises means for gathering and conveying the cuttings away from said machine and depositing said outtings on the mine floor remote from the face in the gob or in any suitable receiving device, such as I have described in a prior application, Serial Number 243,846, filed December 31,1927. 'p i The mining machine 10 comprises a truck portion 11 supported on axlesand wheels in an ordinary manner. An auxiliary supporting frame 14 is mounted for rotation near the forward portion of the truck 11 and has suitable means'thereon for supporting a cutting element 16. Herein said supporting means comprises a plurality of supporting arms 17, 17, having racks 18, 18, thereon. Pinions 19, 19, on the cutting element 16 mesh with theracks 18. The pinions 19, 19 are connectible with a motor 20 carried by the cutting element 16 through any suitable gearing means (which need not be described here since it is no part of my invention), for vertically moving said cutting element in the racks 18 to provide a means for cutting at a plurality of vertical heights. The supporting frame 14 is also rotated by a suitablegear reduction means from a motor 21 on the rearward portion of the truck portion 11 in the well known manner of machines of this type. Therefore, when the frame 14 is rotated, the cutting element 16 is moved in an are which in turn provides a means for sumping a cutter bar 22 having a cutter chain 23 thereon into the coal for cutting said coal.

Referring now more particularly to the novel features of my invention, cuttings gathering and conveying means are provided to gather the cuttings discharged from the outter chain 23 while said cutter chain is cutting a kerf along a mine wall, and discharge said cuttings beyond the machine into the gob or into any suitable receiving device. To aocomplish this a conveying element 25 is detachably supported on the side of the truck portion 11 adjacent the face of the coal when the mining machine is moving parallel to the face of the coal to cut a kerf therein, so

thatsaid conveying element is directly beneath the cutter bar 22 when the longitudinal axis of said cutter bar is perpendicular to the longitudinal axis of the truck portion 11. The conveying element 25 extends to each side of the cutter bar 22 a sufiicient distance to catch all of the cuttings discharged from the cutter chain 23 and discharges said cuttings into a second conveying element 28 at one end of the truck portion 11 and disposed at right angles thereto so as to discharge the cuttings rearwardly of the cutting element 16 when said cutting element is in the position shown in Figure '1. The conveyor element 28 is preferably also supported on the same track which supports the mining machine on a trailer truck29, as

shown. I I t In connection with the conveyor 25, 1 provide a cuttings deflector or apron 30, which is pivotally connected to the outer edge of the conveyor 25, as willhereinafter more fully appear, and is arranged to abut the face of the coal while, the cutting operation is being performed and catch the cuttings discharged from theecutter chain 23 and deflectsai'd cutesi'into theconveying element 25. I

tin V 1 gince one of the purposes of my machine is to cut out dirt bands ona relatively long face and discharge the-dirt cutoutat a point.

away from the face of the coal to prevent said dirt from becoming mixed with the "coal, most of the cutting is done with theinachine moving parallel to the iia'ceof the coal is as indicated in Figure 1 and in most instances it is onlynecessary-that the'conveying ele ment 25 be held on theside of the truck por- ,tion ,11 as is-shown in Figure 1. Y However,

the conveying element 25 may be detachably connectibleto the truck portion llso as'tO.

bemounted on eitherside of said truck portion-in case-it is desired to cut in a direction opposite to that illustrated in Figure 1.

' -The conveying element 25 may be of any suitable type but herein comprises a' belt conveyor 26 of a usualtype well known to the artifixed to thetruck portion ll by means-of an angle piece 27 fixed to the inner side of said conveyor by any suitable means such as rivets "(not shown), andsupporti-ngmember 31 fixed to the under side ofsaid conveyor and truclrportion 11. The angle-27 and supporting member 31 are herein shown as being 'bo'lted 'to the truck portion 11 but maybe held to said truck portion by any well known means. 7 A motor32 isprovided'to drive the i conveyor 26 through drive chains 33' and- 34:

ina manner wellknown to the art."

Thecuttings deflecting means or apron i 7 comprises a plate'35 extending longitudinally of the conveying'element: 25 having-members attached to its lower end pivoted to the "conveying element 25 by means of aipivot rod 37. The plate 35has a plurality. of rotatable "discs 40, 41), yieldably mounted at its outer or free end adapted to engage the face of the coal in all positions of the plate 35 and to follow uneven surfaces insaid coal face id the plate 35 along the face'oi the coal as the cutter bar 22 is cutting a kerf therein. r

" Eachdisc 40 is mounted on the under side of the. plate 35 fwhen'said plate is in such positionthat its free end may engagethe -mine wall on a pin 41 for rotatable movement thereon A hub 42 of theidisc 4:0 rides in a jj'slot 46 on-a supporting member 4A. The pin 41 has aheadle on oneend ther'eof'and is slidable in a slot 43 in the plate 35 and the "slot 43 in the supporting 'member 44. A

member 47 is threaded on the opposite end of pin rod 48 base. head/i9 at one of its ends and passes through a hole in a depending portion 50 of the supporting member 4A and its opposite end is threadedin the member 47. A spring 52 surrounds the rod 4118 anclis interposed between the'member at? and the dependingportion 50 of: the support- ,ing member 44 to keep the disks 10 man extreme forwardposition on the plate 35-and allow said discs to move rearwardly on said plate when obstructions "or uneven spots are encounterd on the face of the coal, and guide the plate 35 as they travel longitudinally along said'coalface.; I 7 e V The trailer truck 29 is supported on axles 56and'track wheels 57, '57, and is adapted to be attached to the fo-rward'end of the truck portion 11 sosaid truck may be moved along with'the mining machine as the cutter bar 22 is cutting akerf in'the mine wall. suitable means maybe used toconnect the truck 29 to thetruc-k portion 11. I The means herein shown comprise a bar 58 pivotedto the truck portion llto swingabout a horizontal axis at 59 at one end and pivoted to a clevic 60 on-the trailer truck 29 on its opposite end by means of a removable vertically disposed pivotal pin .61. T The conveying element 28 is pivoted to the trailer truck 29 near itscentral Any portion on a shaft 62 journaled on an axia extending longitudinally of said trailertruck,

so saidconveying elementma'y' be'moved in a horizontal position whenit is desired to transport the trailer truck 29 about the mine. The conveying element 28 1s hereinshown as a belt conveyor 65 of a usual type well known to the art, and extendsfrom the for- "ward portion'of theconveying element 25 to a point beyond the rearward portion of the cutting element 16 at right angles to the longitudinal axis of the truck portion 11 as shown in Figure 1. The conveyor 65 is drivenbyan 'eiectric motor 66in a well chains .67 an d'6 8. I j V From the above description, it may be seen that my invention comprises a cutting machine of the'slabbing or over-cutting type vknown manner, as,'for instance, by drive having incorporated therewitha means to catch anddis'charge the cuttings into the gob beyond the mining machine or load said outtings into any suitable receptacle. Said invention is especially. adapted for use in cut- .di'rt hands out of coal. The cutter chain .23 on the cutter bar 22 is adapted to cut into the dirt band and expel said dirt from the 'kerf formed by said cutter chain. The dirt cut 'out'by the cutter'chain 23 is caught by the cuttings deflecting means 30 anddeflected to the conveying element 25 which deposits these cuttings into the conveyingelement 28 on the trailer truck '29. The conveying element 28 in turn deposits said cuttings into the gob or anysuitable receiving device. .It may now be seen thatmy invention provides a simple means of separating the dirt from the coal and conveying said dirt away from the face 'ofthe'coal'and that'my invention is as adaptable and useful in'loading the slack-"coal cuttings as in separating the dirt from thecoa-l.

parts may be altered or changed without departing from the spirit orscope thereof.
